Rail Transit Mobile Toilet

Rail transit mobile toilets are mobile sanitation facilities that combine multiple technical solutions to adapt to different application scenarios, aiming to address the toilet needs during the construction and operation of rail transit, as well as in special scenarios.

Technical Solutions

1. Combustion Treatment Technology: The "Rail Transit Mobile Intelligent Toilet" solution adopts a microwave-based fecal combustion treatment technology, aiming to achieve real-time pollutant treatment on high-speed rail and other rail transit vehicles, reducing the pressure of waste storage and transportation.
2. Vacuum Toilet Technology: The vacuum toilet equipment developed by Sichuan Zhongneng Environmental Protection Technology Co., Ltd. has been adapted for train operations on tracks. It achieves efficient collection and sealed storage through vacuum negative pressure sewage discharge technology, reducing odor and pollution risks. Its vehicle-mounted (electric vehicle) vacuum toilet further optimizes the power and sewage discharge systems, providing stable operation capabilities and representing a key breakthrough in rail transit support equipment.
3. Integrated Technical System: Mobile toilets typically integrate water circulation treatment, waste storage and preliminary treatment, energy supply, and environmental control subsystems. For example, waterless or water-saving technologies (such as vacuum collection and foam sealing) can reduce dependence on municipal water supply and drainage networks; waste is chemically degraded, biologically fermented, or sealed for storage and then centrally transported for disposal; energy supply utilizes solar panels combined with energy storage batteries to enhance environmental friendliness and sustainability.

Application Scenarios

1. Rail Transit Construction Phase: For instance, during the preparation phase of the Zhengzhou Metro Line 7 Phase I project, 21 mobile toilets were leased to cover all 21 stations along the line, meeting the toilet needs of construction workers and temporary visitors. The lease period included full-process services such as transportation, cleaning, and maintenance.
2. Operational Emergency Support: Vehicle-mounted self-propelled mobile toilets, with integrated power systems and storage facilities, can quickly respond to巡回 (patrol) service demands and are suitable for temporary replacement during sudden passenger surges or fixed toilet maintenance.
3. Large-scale Events and Temporary Needs: Modular assembled mobile toilets can be quickly set up using standard components, providing multi-stall temporary restrooms commonly seen at large-scale events or exhibitions around rail transit hubs.

Classification and Characteristics

1. Trailer-mounted: Relies on towing equipment for relocation and is suitable for medium- to short-term fixed-point services, such as construction sites or temporary stations.
2. Vehicle-mounted Self-propelled: Integrates power and sewage discharge systems, capable of autonomous movement, and is suitable for patrol services or emergency responses.
3. Modular Assembled: Quickly assembled using standardized components, with flexible stall quantities, often used in high-density pedestrian scenarios.
